[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] According to an embodiment of the present utility model, an intelligent sofa backrest posture adjustment device is provided.

[0022] The present utility model will be further described in conjunction with the accompanying drawings and specific embodiments. As Figures 1 - 3 shown, an intelligent sofa backrest posture adjustment device according to an embodiment of the present utility model includes an intelligent sofa body 1. A seat cushion frame 4 is provided at the inner bottom of the intelligent sofa body 1, and the left end of the seat cushion frame 4 is hinged to a backrest plate 5 through a hinge. Sofa cushions 14 are provided on the surfaces of the seat cushion frame 4 and the backrest plate 5, and a leather cover 6 wraps around the periphery of the seat cushion frame 4, the backrest plate 5 and their sofa cushions 14. Metal frames 2 are fixedly connected to both the left and right sides of the intelligent sofa body 1. A servo motor 10 is installed in the metal frame 2 corresponding to the area of the seat cushion frame 4, and a hanging ring 7 is fixedly connected to the metal frame 2 corresponding to the area of the backrest plate 5. A steel wire rope 9 is installed on the hanging ring 7 through a rope buckle. The output end of the servo motor 10 is fixedly connected to a winding drum 11, and the winding drum 11 is wound around and connected to the steel wire rope 9. An electric push rod 12 is fixedly installed on the inner side surface of the metal frame 2, and a clamping jaw 13 is fixedly connected to the bottom of the electric push rod 12, and the inner side surface of the clamping jaw 13 abuts against the steel wire rope 9. The lower part of the left end of the seat cushion frame 4 is hinged to a telescopic rod 15, and the top end of the telescopic rod 15 is hinged to a sliding sleeve 17. A sliding rod 16 is fixedly connected to the side of the backrest plate 5 facing away from the sliding ring, and the sliding sleeve 17 is sleeved on the sliding rod 16 of the backrest plate 5. The intelligent functions and components of the intelligent sofa body 1 are the same as those in the prior art or can be implemented using the prior art. Since there are mature products, no further explanation of its principle will be made. Among them, at least two groups of telescopic rods 15, sliding rods 16 and sliding sleeves 17 are provided to ensure the reliability of the angle adjustment between the backrest plate 5 and the seat cushion frame 4;

[0023] In one embodiment, a plurality of guide sleeves 8 are provided at the edge of the side of the backrest plate 5 with the hanging ring 7, and each guide sleeve 8 is sleeved on the outer surface of the steel wire rope 9. Through the arrangement of the guide sleeves 8, the steel wire rope 9 can be constrained on the backrest plate 5 to avoid the situation that the steel wire rope 9 is taut during the winding and unwinding process and damages the sofa structure.

[0024] In one embodiment, a pleated portion 18 is sewn on the part of the leather cover 6 facing the telescopic rod 15, and the pleated portion 18 is arranged in a wavy structure. Through the arrangement of the pleated portion 18 in a wavy structure, the leather cover 6 can adaptively "stretch" to meet the angle adjustment between the backrest plate 5 and the seat cushion frame 4.

[0025] In one embodiment, a U-shaped hinge seat is provided at both ends of the telescopic rod 15, and hinge blocks are respectively provided on the seat cushion frame 4 and the sliding sleeve 17 corresponding to the U-shaped hinge seat. A pin shaft with an opening pin is inserted between the U-shaped hinge seat and the hinge block. The principle of the telescopic rod 15 is a known technology in the prior art, and there are mature products, so no further explanation of its principle will be made. By using the telescopic rod 15, it can adaptively stretch during the angle adjustment between the backrest plate 5 and the seat cushion frame 4 and has a damping effect.

[0026] In one embodiment, the jaw 13 is integrally arranged in a U-shaped structure, and a grid-shaped anti-slip surface is arranged on the inner side surface of the jaw 13, and the anti-slip surface of the jaw 13 is in contact with the steel wire rope 9. Through the arrangement of the jaw 13, the steel wire rope 9 can be limited, and the reliability of the overall intelligent sofa body 1 after posture adjustment can be maintained.

[0027] In one embodiment, a control panel 3 is fixedly installed on the side wall surface of the intelligent sofa body 1, and the output ends of the control panel 3 are respectively electrically connected to the servo motor 10 and the electric push rod 12. The control mode of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common general knowledge in the art, and the present utility model is mainly used to protect mechanical devices, so the control mode and wiring arrangement of the present utility model will not be explained in detail.

[0028] Working principle:

[0029] During use, the servo motor 10 built in the frame is started to rotate through the button on the control panel 3, so that the reel 11 at the output end of the servo motor 10 winds or unwinds the steel wire rope 9. Since the steel wire rope 9 is connected to the hanging ring 7 of the backrest plate 5, and the steel wire rope 9 is inserted through several guide sleeves 8 of the backrest plate 5, and the backrest plate 5 is rotatably connected to the seat cushion frame 4 through a hinge. As the steel wire rope 9 is wound and unwound, the included angle between the backrest plate 5 and the seat cushion frame 4 is increased or decreased. When the steel wire rope 9 is wound, the included angle between the backrest plate 5 and the seat cushion frame 4 is decreased, so that the backrest plate 5 part of the intelligent sofa body 1 fits the user's back more closely. When the steel wire rope 9 is unwound, the included angle between the backrest plate 5 and the seat cushion frame 4 is increased, and the intelligent sofa body 1 can be used as a sofa bed. After the adjustment of the included angle between the backrest plate 5 and the seat cushion frame 4 is completed, the electric push rod 12 is started to extend, so that the jaw 13 of the electric push rod 12 presses and locks the steel wire rope 9 with the anti-slip surface, and the reliability of the whole body after the backrest posture adjustment is maintained. At the same time, since the telescopic rod 15 hinged on the seat cushion frame 4 is rotatably connected to the sliding sleeve 17 of the backrest plate 5 through a hinge, and the sliding sleeve 17 is sleeved on the sliding rod 16 of the backrest plate 5. When the backrest plate 5 and the seat cushion frame 4 rotate, the telescopic rod 15 telescopically adapts, and the damping effect during the posture adjustment stage is maintained by the sliding of the sliding sleeve 17 and the sliding rod 16, which is beneficial to increasing the stability and reliability during the posture adjustment stage.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
